WEG reinforces its position as a strategic supplier in power generation, transmission, and distribution systems in Brazil by delivering one of the largest alternating current transformer banks ever installed in the country: three single-phase 500 MVA transformers at 525 kV, totaling 1.5 GVA of transformation capacity for the Assis Substation, in partnership with TAESA – Transmissora Aliança de Energia Elétrica S.A. 

This large-scale project involved close technical cooperation with TAESA, covering all stages from project development and manufacturing to logistics planning, transportation, and commissioning of the equipment. Manufactured at WEG’s plant in Betim, state of Minas Gerais, Brazil, each transformer—approximately 300 tons—traveled about 800 km to the installation site in Assis (São Paulo), in a highly precise and complex logistics operation. 

The transformers are part of the substation’s second transformation bank and play a key role in adapting the voltage level from 440 kV to 525 kV, strengthening one of the most important corridors of the Sistema Interligado Nacional (SIN). This additional transformation capacity contributes to the expansion of the reliability and robustness of the Brazilian electrical system, benefiting major consumption centers and improving grid stability. 

The delivery of this three-phase transformation bank represents a milestone in engineering and applied technology, reflecting WEG’s expertise in high-voltage and large-scale solutions, as well as the trust placed by one of the country’s leading transmission players. The partnership with TAESA reinforces the importance of cooperation between industry and the power sector to enable critical infrastructure that ensures the security and sustainability of energy supply in Brazil.
